It seems Adobe still has no clue how to help us.
I bought a new laptop recently and installed CC on it. It works fine on the laptop but is still lagging on my main computer.
Hopefully Adobe will figure something out. They should realize that for each individual taking the time to find this forum and writing a post in here, there is probably a few thousand more who are just frustrated and SILENT but with the same problem...
Let's hope it gets fixed...
